g A'-fLYEIi STEINMETZ, 0F nveizsvinnninmnnaa ArrARii'rU-sjnon@H aiiniiiiidAND.s'rbiiiiveffilirLKfjnfJr Be it Aknown that l, GEORGE MiiirWnLL, a citizen oi' theUnited States7 residiiigrat -E\faiisville, in the county of Vanderburg -and State oflndiana, haveinvented a new and useful Apparatus `for .Handling and- Storing Mill; of ywliiclithe following ji's a specification.;

-This invention relates to'an apparatus" for handling and storing milk, one'cf its objects being to provide means whereby-ther' inillrcaiibe caused 'to flow from the-'covvv directly .to a containerv provided therefor,

.said container being hjermetieally sealedand having a partial. vacuum: therein `whereby the inilkpcanV bevkept either at :its natural temperature for la considerable per-rod.v of vtime or can, if preferrechbe cooled without ContactV at any time withtheyexternal atmosphere; storedVa-n'd packed ready for ship# pingto the consumer. l

A further object is to sopieparey tliedco'ntainer that any 'air remaining. therein-prior .to'theadinission of the milk will be thoroughly'sterilized and of the desired teniperature. y y

vlith the foregoing and other objects in view.1 the linvention consists in' certainVY novelv details of construction and combinations of pai-tswhicli will be yhereinafter mor'efully described and pointed out inthe claims.

in the accompanying drawings they preferred form of the containerv and apparatus used in connection therewith has i been shown.

. In said drawings Figure l is a section. through the con-4 tainer packed for shipment after having `been filled with milk.

Figure 2 is a section through the con'- tainer removed from its packing case and showing its several parts separated.

Figure S is a view showing tlierelative positions or' the parts during the filling of the container.

Referring tothe figures by characters of reference l designates `the outer-casing of the container which canA be made of glass,

porcelain, or any other suitable Vniaterial,

there being provided at the upper end of this outer casing a thickenedwallQ the Yup-y per `face of which is inclined inwardly and downwardly toward the center as shown at 3 thus to provide a seat which vis tapered.

This seat is adapted to support agasket l.4

merged .into a coolingcoil such as' indicated ior storing cooled milk. There the milkis l to be retained at bodypheat or substantially l body heat the 'f coil 18 obviously is not used for cooling purposes.

In lcarrying out the process the parts of the containerV are separated ina' iooicfimcon.'{Q }l tainingsterilized-air ofa temperature equal jte or slightly above thefnorinal heatfofthe`v milk.' `While in this' room theparts` are?

toy-theA cqver 10` and communicateswith 'the the flange 5, the cover 10-is-placed in posi tion, and the parts 'are bound together tightly. By means of the pump 13 apartial vacuum is y,formed within the inner casing v 6 after which the cup 17 is applied to the cow and the milk caused to flow therefrom through-the tube 16 and into theinner casing 6. .Y After the casing has been entirely or partially filled the pump 13 and the tubev 16 are removed and are replaced by the plug y14 Yandv another plug 19 respectively.

with. the milk thus delivered im@ the inner casing 6-it is kept practically at body yheat and as it has not had an opportunity :to vcomeinto Contact with any of the'eX- Vternal atmosphere but only with the small amount of sterilized air left within the partial vacuum*7 it will be apparent that when delivered to theconsumer it will be in a pure wholesome state. In transporting the.l container it can be placed in a case 2O ofl fiber, wood or the `like provided with a packing v21 of straw, asbestos or'any otherV heat insulating'material so that'thev heat of the milk will be retained for a long period. Y f

When `it is desired to cool the milk while delivering it to the container but without bringing it into Contact withl the external atmosphere, `it is not necessary to assemble the parts of the container in av room containing'heated air although the air should be sterilized before the parts are assembled.`

The air is then partly extracted by means ofthe pump 18 and the milk,lwhen flowing nto the inner casing 6 caused to flow through the cooling coil 18 so that the temperature will be lowered to a desired degree. The parts are then disconnected from the cover 10, said cover is sealed and the container is ypacked as heretofore described v and thenl shipped to the consumer.

It is to be understood that various modications` may be made in the ,construction andY arrangement of lthe parts without departing from the spirit Vof the invention yas claimed.

tube 16 can be provided with double vwalls spaced apart by hea-tinsulating material or' with aV partial Vacuum between them so It is to be understood thatif desiredl they that the milk will not be Vcooled. when the c cooling apparatus -is not in use.

Vihat is claimed is.:-.-

1. A container for milk and the like comprising nesting inner and outer casings -hav- Aing an air space therebetween, a hollow coverextending over the casings and connected thereto7 means detachably mounted on- `the cover for extracting lair from the inner casing, and lmeans detachably connected to the cover for directing fluid into the inner casing following the extraction of the air;`

extending over the innerl and outer casings, Y

sealing means betweenthe flange and cover and .between the vflange and the vouter cas# l ing, means extendingv through the flange and `engaging the cover and the wall of the outer casing for binding the'parts togetherV to seal the contents *of ,l the inner casing,

means connected tothercover for withdrawn ing air from the `inner casing, and means connected to the cover for directing liquid into the inner casing following they withdrawal of the air.

In' testimony that l claim the foregoing Vas my own, I have hereto affixed my `signature 1n the presence of two witnesses.`
